3.3.5.1 PLC Transmission Circuit

The transmission stage adapts the EMIT signals and amplifies them. In the PL360G55CF-EK board, see Figure 3-11, it is a single branch composed of:

Driver: It adapts the EMIT signals to either control the amplifier or to be filtered by the next stage
Amplifier: A Class-D amplifier generating a square waveform from 0 to 12V
Bias and protection: It provides a DC component and provides protection from received disturbances

The transmission stage is followed by a filtering stage.
